You are most welcome to suggest something more suitable.
Disabled cyclist; with one bad choice behind her, needs help with a new bike

Lightweight EAPC in general for the masses don't exsist , let alone for soemone with some knd of dissability/impairment. It is worse when that dissability/impairment involves lack of muscle power, stamina or just weakness due to severe repiratory issuues.
The need for extra power and range to overcome the short comings that a dissabled/impaired rider requires all add weight .
Though lighter weight EAPC's do exist they are aimed at the fitter /lighter rider using lighter weight materials and components who need minimal assistance.
One main component is the battery that tends to be quite small cappcitiy wise and approx. 2kg -2.5kg lighter then most batteries. Also these bikes will be lighter by having no mud guards, heavy suspension , racks. Lighter rims and wheel sets will be used and skinny lighter tyres.
For an impaired person, weight such as carrying, lifting or manouvering heavy items doesn't practically go in hand as balance is often involved.
One reason why trikes or quad wheeled vehicles are used.
Any bike is going to need compromise , the issue is Katy still want's a big wheeled bike that alone makes manouvering a little more awkward then small wheels.
Problem is small wheels often means a bike is still heavier as other areas are stiffened up to compensate for size, safety & reliability.
The weight saving for large wheeled vs small wheeled is very little.

If I ever manage to score a Dahon Presto SL (the SL has a derailleur), I'll throw on a BBS01B kit. Here's a fully loaded Presto Light at 11kg. Wheelbase is 3in shorter than my Helios, but longer than their newer bikes. If throttles become legal after the government consultation, it'll be a 11kg + 5.6kg BBS01B + 3.6kg 19.2Ah/691Wh battery = 20.2kg epic fast hill climbing folding commuter moped with 43+ mile range. Heavier with a derailleur by a bit, laughing in the face of the hideous green congealed snot coloured Rambletta frog bike with it's small low range battery and comparatively puny motor system.

Dahon Custom Built Dahon Prestolite D3 Brushed Aluminium SLIGHTLY USED
Dahon Prestolite Frame Such fun to ride, and so much better to ride than the more recent 16" Dahon bikes (like Eezz and Jifo) due to their longer wheelbase and more sensible gear ratios.

I have a converted gravel bike thta comes in at 13.5kg , the kit in all is only 2.5kg approx. but it is wholly unsuitable for a dissabled/impaired rider.
A step thru bike simply doesn't exsist that is as light because of extra stiffening elsewhere to ensure the bike is safe and this adds to the weight. For the masses expensive and cheap don't go together and if any are found or made will be for a niche market.

This 17.5 kg Fiido looks intriguing, low step over, but tiny wheels. 7.8Ah/280.8Wh battery, so it's also low range:

Exactly all the merits that Katy doesn't want , why she doesn't want small wheels to try and make life a bit easier we don't know but the main issue apart from the bike wheel size and type is range anxiety so the need for a heavier battery.This 17.5 kg Fiido looks intriguing, low step over, but tiny wheels. Low range too:

It matters not if a battery is 36v 10s 5p and of 11, 13, 15 or 17.5 ah , the battery weight will be exactly the same bar the odd gram. The only weight saved is a 200- 300 grams if 10s 4pis used.
Oh well, maybe someone else will come up with something which ticks all of the boxes on her requirements list.
It is a bit lighter , though with a tiddly 7.8ah/280wh battery a couple of kg have been saved, but the claimed range for said battery is nowhere good enough for an impaired rider who will be using it most likely at full power. It would likely get Katy as far as 15 miles before recharging is needed.This 17.5 kg Fiido looks intriguing, low step over, but tiny wheels. 7.8Ah/280.8Wh battery, so it's also low range:

Although I have asthma , It doesn't affect me riding so I can get away with using very low power (PAS1) 13% power of 22a on flat terrain, I can manage 30 miles from a 6ah/260wh battery.
Sadly far from helping Katy in the most part sensible options aren't being suggested and replies certainly aren't taking in to account that the assistance she needs is pretty much max power to over come the lack of stamina/muscle input .
Weight wise there are few choices for big wheeled step thru bikes and most will be at least 22kg.
For 40 miles on mostly full power we will be looking at 15ah /540wh or 17.5ah/630ah batteries.

And from very long experience of similar inquiries in here, we know that the disabled rarely understand the limitations of physics, current technology and the regulations of bureacracy free electric assist bikes. They mean that they are only suitable for those who can still cycle normally but just need a little help at times. Hence the assist word.
Bureacracy free electric assist bikes are not disability vehicles, in too many ways falling well short of the needs that can arise to fulfill that purpose. That is why Katy is having such difficulty in finding a suitable one. Put simply, the impossible doesn't exist.
Everything we suggest will have some of her necessities unmet.

it is possibly because of the comfort of bikes with big wheels.
Suspension on a 20" bike will never be good enough for someone with back problems, worse on 16".
The needs are as have been pointed out already.
- Large wheel format = tick, options available.
- Sit up and beg/dutch style swept back bars = tick , options available .
- Step thru design = tick , options available.
- Power = tick , options available but must be hub type with throttle as rider has muscle /stamina issues. No use suggesting torque multiplier systems .
- Range needed up to 40 miles for return journeys have been implied, shorter journeys are under taken but pointless in suggesting a low capacity/range battery.
- Lightweight , manouverability = no tick as most bikes even small wheeled are heavy and don't meet users needs.
In that case, it's pointless suggesting the hideous green congealed snot coloured Rambletta frog bike with it's small low range battery. Suggested three times by three members, including @saneagle, who looks bigger and stronger than baldy Jason from The Gadget Show.

The up cycling of the Crusa hub motor is an option if a suitable stepthru candidate can be found , how ever the base bike has to satrt off light a sone would be adding the hub which is circa. 4kg and a battery downtube if one will fit another 3 - 4 kg and one soon sees why it is almost imossibe to get under 20kg . Add racks,mudguards etc,etc and the weight goes up and up.
Ok, I spoke to my brother who hadn't really understood my physical limitations or maybe I hadn't explained them carefully enough
We are selling the Fazua after he let's me know what kit is on it (any suggestions of places to list it gratefully received - not sure facebook marketplace is the best idea)
I test rode on Orbea today and was pleasantly surprised I can deal with the centre of gravity but I dont think it has enough umph for hills
It also felt very low in the road and somewhat vulnerable, the crusa is very definitely higher and more visible - prob only a few inches but my head feels above the car drivers
This shop suggested a volt, Burlington, I think which I had no energy to ride today but I'll go back and try it, I wheeled it around and although lifting would be impossible, I could see me getting it parked on on a train and the weight is between my hands not 2 ft behind me

Guerney has you on "Ignore", so he won't see your question or any of your posts past or present. He says he has me on ignore too.
Why he thinks it's ok to comment adversely on someone or their products when they cannot reply to him I don't know. To me it is very ill mannered.
I'm reporting my own post to Admin since they may have a view of the propriety of such behaviour.
